Abstract

The invention relates to a vehicle drive rear axle brake dustproof cover composite mold and a compound process. The mold is divided into a mold upper half part and a mold lower half part; the mold upper half part comprises a mold handle, an upper template, a guide sleeve, an upper cushion plate, a forming unloading spring, a blanking unloading spring, an upper fixed plate, an inner guide column, ablanking unloading plate, a blanking convex mold, a forming unloading plate, a pressing convex point concave mold, a punching convex mold and an inner guide sleeve; and the mold lower half part comprises a pressing convex point convex mold, a mold corrector, a composite mold, an ejector rod, a stop pin, a blank holder, a blanking concave mold, a guide column, a lower cushion plate and a lower template. The mold precision and life and the product quality are improved by adopting such structures as a mold correcting stop port and the mold corrector for automatically correcting mold gaps. A traditional compound process with three procedures (blanking and drawing procedure, punching procedure and convex point pressing procedure) is replaced.

Description

technical field [0001] The invention belongs to the field of mechanical equipment, and relates to a manufacturing mold for a brake dust cover, in particular to a composite mold and a composite process for an automobile drive rear axle brake dust cover. Background technique [0002] The brake dust cover is welded to the brake base plate by projection welding, mainly to prevent dust, water, and rust for the brake base plate assembly, and to make the car more durable and durable. The traditional production method of the brake dust cover is divided into four processes. The process flow is: blanking → blanking. Deep drawing → punching → embossing to meet the product design requirements. This not only requires a large number of molds to be installed, but also takes a long time to produce, and also requires multiple material distributions between multiple devices, resulting in low production efficiency. The present invention is just based on the optimization considerations of the ...
